Expression data of multiple sclerosis patients receiving intramuscular Interferon-beta-1a therapy [U133 A and B]

ABSTRACT: The purpose of this study was to characterize the transcriptional effects induced by intramuscular IFN-beta-1a treatment (Avonex, 30 µg once weekly) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 24 MS patients within the first four weeks of IFN-beta administration. Keywords: Multiple sclerosis, Interferon, Pharmacogenomics, Affymetrix

Expression data of multiple sclerosis patients receiving Interferon-beta therapy

Project description:The purpose of this study was to characterize the transcriptional effects induced by intramuscular IFN-beta-1a treatment (Avonex, 30 Âµg once weekly) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 24 MS patients within the first four weeks of IFN-beta administration. Keywords: Multiple sclerosis, Interferon, Pharmacogenomics, Affymetrix EDTA blood samples were taken from all patients immediately before first, second and fifth IFN-beta injection. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labelled and hybridized to Affymetrix Human Genome U133 A and B arrays to quantify the mRNA levels.

Expression data of multiple sclerosis patients receiving subcutaneous Interferon-beta-1a therapy [U133 Plus 2.0]

Project description:The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1a treatment (Rebif, 22 µg or 44 µg three times a week) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 12 MS patients within the first two years of IFN-beta administration. EDTA blood samples were taken from all patients immediately before first and second IFN-beta injection as well as after 1 month, 1 year and 2 years. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labeled and hybridized to Affymetrix Human Genome U133 Plus 2.0 arrays to quantify the mRNA levels. This GEO entry provides the U133 Plus 2.0 microarray data.

Pharmacogenomics of IFNb therapy

Project description:This experiment set is used for the manuscript entitled: Pharmacogenomics of Interferon-b therapy in multiple sclerosis: Baseline IFN signature determines pharmacological differences between patients. In this study we generated and analyzed pre- and post- IFNb treatment gene expression patterns of RRMS patients with the aim of identifying pre-existing and/or drug-induced signatures that will allow us to make predictions on the expected pharmacological effects of IFNb treatment. We show that the expression level of IFN response genes prior to treatment, determines the pharmacological differences between patients with MS at the molecular level. A group of 16 Dutch patients (10 females and 6 males) with clinically definite relapsing-remitting MS was recruited from the outpatient clinic of the MS Centre Amsterdam. Mean age at start of IFNb therapy is 40.6 +/- 7.7, mean EDSS is 2.3 +/- 1.3 (range 1-6). Blood samples were obtained just before treatment and 1 month after start of the therapy. Patients received Avonex, Betaferon, Rebif 22 or Rebif 44. A compound treatment design type is where the response to administration of a compound or chemical (including biological compounds such as hormones) is assayed. Compound Based Treatment: Before and 1 month after IFNb therapy Keywords: compound_treatment_design Complex

Expression data of multiple sclerosis patients receiving Interferon-beta therapy

Project description:The purpose of this study was to characterize the transcriptional effects induced by subcutaneous IFN-beta-1b treatment (Betaferon, 250 µg every other day) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 25 MS patients within the first two years of IFN-beta administration. EDTA blood samples were drawn from all patients immediately before first, second, month 1, 12, and 24 IFN-beta injection. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labelled and hybridized to Affymetrix Human Genome U133 A and B arrays to quantify the mRNA levels.

Expression data of multiple sclerosis patients receiving glatiramer acetate therapy [U133 Plus 2.0]

Project description:The purpose of this study was to analyze the transcriptional effects induced by glatiramer acetate treatment (GA; Copaxone, 20 mg injected subcutaneously once daily) in blood monocytes of patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of monocytes from 8 MS patients within the first two months of GA administration.

Expression data of multiple sclerosis patients receiving Interferon-beta therapy [miRNA-2_0]

Project description:The purpose of this study was to investigate the expression dynamics of mRNAs and microRNAs in response to subcutaneous IFN-beta-1b treatment (Betaferon, 250 Âµg every other day) in patients with clinically isolated syndrome (CIS) suggestive of multiple sclerosis (MS) or relapsing-remitting type of the disease (RRMS). By using Affymetrix microarrays, we obtained microRNA expression profiles of peripheral blood mononuclear cells from 3 MS patients within the first month of IFN-beta treatment. EDTA blood samples were taken from all patients immediately before first IFN-beta injection as well as after 1 month. Total RNA of Ficoll-isolated peripheral blood mononuclear cells from each sample was extracted, labeled and hybridized to Affymetrix GeneChip miRNA 2.0 arrays to quantify the expression of small non-coding RNA transcripts. This GEO entry provides the GeneChip miRNA 2.0 microarray data.
